モヤモヤ

• Reading: モヤモヤ
• Romaji: moya moya
• Pronunciation: /mo.ja.mo.ja/

Meaning

A hazy, unsettled feeling — vague frustration, unease, or foggy confusion that you can't quite put into words.

モヤモヤ perfectly describes that nebulous feeling of something being not quite right but you can't pinpoint why. It's the emotional fog after an argument that wasn't fully resolved, the unease about a decision you're not sure about, or the frustration of not being able to articulate what's bothering you. The word captures the mental equivalent of actual moya (fog/haze) — something obscuring clarity. It's the opposite of スッキリ.

Examples

1. なんかモヤモヤするんだけど、理由がわからない。 Something feels off but I can't figure out why.
2. あの話し合い、モヤモヤが残ったままだな。 That discussion left me with an uneasy feeling that still hasn't gone away.
3. モヤモヤしてる時は散歩するとスッキリするよ。 When you're feeling unsettled, going for a walk helps clear your head.

Do Say

• モヤモヤするからちゃんと話し合おう (I feel unsettled so let's talk it through properly)
• ずっとモヤモヤしてたけどやっとスッキリした (I'd been feeling unsettled for a while but I finally feel clear)

Don't Say

• はっきりした怒りに「モヤモヤ」は弱い (Using 'moya moya' for clear, strong anger is too vague — it's for undefined unease)

Common Mistakes

• Confusing モヤモヤ with イライラ — イライラ is clear irritation while モヤモヤ is unclear, foggy discomfort
